Hi Mathias, it’s pretty straightforward to get the curvature values along a curve. Here’s a script I recently wrote that demonstrates how to build a colored mesh graph visualising curve curvature. If you output points and vectors from the component (i.e. the variables on line 81), that should be enough to construct anything you might need:
